Morgan, Drew Participate in Challenger Center Event

(NASA) – STS-118 crew members will hold class in space and transfer cargo between the International Space Station and Space Shuttle Endeavour today. Preparations for a possible spacewalk to repair a small ding in Endeavour’s thermal protection system tiles will also occupy a considerable part of today for the crew.

Mission managers have not decided that a repair spacewalk will be needed. But to prepare for that possibility, the crew members will begin to get ready to do the repair, should managers determine that is necessary.

The managers did decide to move the flight’s fourth spacewalk from Friday to Saturday. If the repair isn’t done, that spacewalk will see installation of two antennas and removal of one, installation of a stowage stand for the shuttle’s orbiter boom sensor system and other tasks.

Mission Specialists Barbara Morgan and Alvin Drew participated in an education event this morning with students at the Challenger Center for Space Science Education in Alexandria, Va. Morgan, an educator who became an astronaut, was first selected by NASA in 1985 as the backup to Teacher in Space Christa McAuliffe.

Following the Space Shuttle Challenger accident in 1986, Morgan continued to work with NASA on educational activities and returned to teaching elementary school in Idaho. She was selected as an astronaut by NASA in 1998. Family members of the Challenger crew have been invited.

Morgan is being honored with the President George H.W. Bush Leadership Award, the center’s top award.

Morgan and Drew also talked with reporters representing Associated Press Television, Reuters and Idaho Public Television.

The STS-118 and Expedition 15 crew will continue the cargo transfers that began shortly after Endeavour docked Aug. 10. Endeavour delivered supplies and equipment to the station, most of which were located in the pressurized Spacehab module in the payload. Spacehab will carry items, including science experiments, back to Earth.

This afternoon, the crews will enjoy some well-deserved time off.

Mission Management Team Update

Mission Control told Space Shuttle Endeavour’s crew Wednesday that STS-118’s fourth spacewalk will be moved to Saturday. The decision gives the STS-118 and Expedition 15 crew members an extra day to prepare for the spacewalk, which was added to the mission after the STS-118 crew arrived at the station.

Mission managers in Houston continue to consider whether a spacewalk will be needed to repair a small gouge on Endeavour’s heat shield tiles. Before going to bed Wednesday, the crew was informed that managers have decided the next spacewalk will be moved from Friday to Saturday, but that they haven’t decided whether Saturday’s spacewalk will be devoted to tile repair or get-ahead tasks.
